“Sometimes we make sure that we catch enough rainwater to use or we would have to search out the creeks to for water clean enough to drink,” said Guyanese villager Fabian George in a June interview with the United Nations University. The negative effects of a mining boom fueled by surging gold prices have become so widespread in the small South American country, which is about the size of Idaho, that the government has temporarily stopped issuing new gold and diamond mining permits.

The ban, which was announced on July 6 and is still in effect, will last until officials are able to complete a review “of the current management/oversight arrangement of river and tributary mining.” A statement released by the Guyanese Ministry of Natural Resources and Environment explained that “damage caused by increasingly irresponsible mining in Guyana’s rivers and tributaries,” has been a cause of major concern for citizens who depend on them to survive.

Guyana, a former colony of both the Netherlands and the United Kingdom, has a population that is predominantly split between people of African and East Indian descent who were recruited as indentured servants for the tea industry during the 19th century. Amerindians – indigenous Guyanese people – made up just nine percent of the population, as of the most recent census in 2002. A vast majority of Guyanese (71.5 percent) live in rural villages, most of which are located near the coastline. The remaining population resides in the capital, Georgetown, or one of four other urban centers.

While mining is responsible for just nine percent of the country’s GDP, it accounts for almost 60 percent of exports. Gold, bauxite (the precursor to aluminum), and diamonds are extracted and exported to countries including the United States, Canada, and the United Kingdom. In 2011 Guyana produced 363,000 ounces of gold, which represents a 23 percent increase since 2009 and can be attributed “to consistently active mining by small- and medium-scale miners that benefited from the continued increase in gold prices on the international market,” according to the U.S. Geological Survey. The Communities and Small Mining Initiative reports that more than 15 percent of Guyanese citizens economically depend on small-scale mining to support themselves.

Dredging the Jungle

These small-scale operations, also known as artisanal mines, generally employ rudimentary methods to extract and process minerals, as opposed to large scale industrial operations. As of 2011 there were less than 10 industrial-scale companies with any sort of presence in Guyana, while the number of licensed artisanal miners is more than 14,000, according to the government. Although the latter usually consists of just a few workers, they are also incredibly environmentally destructive.

The methods used most by artisanal miners in Guyana begin in one of two ways, according to the Blacksmith Institute: either large water hoses are used to quickly erode a plot of land or barges are used to dredge up sediment from the bottom of a river. Then, they “combine mercury with gold-laden silt to form a hardened amalgam that has picked up most of the gold metal from the silt. The amalgam is later heated with blow torches or over an open flame to evaporate the mercury, leaving small gold pieces.”

The environmental impacts of artisanal mining in Guyana are well-documented and include “drastic increases in the sediment content of river water, increased levels of mercury in river water, creation of artificial sandbars in rivers, deforestation and degradation of land fertility, and mosquito infestation and malaria,” according to a Harvard Human Rights Program study.

A report issued by the Guyanese Ministry of Natural Resources and the Environment last month noted that current environmental problems associated with mining operations include, “widening of the river channel[s] and weakening of soil at river banks resulting in toppling of trees into the river course, blockages and changes to the main river channels resulting in un-navigable channels in the dry seasons.” High levels of turbidity, which is a measure of water clarity, have resulted in the deaths of some fish species that serve as a primary food source for riverine Guyanese communities.

The health of Guyanese rivers and streams is of particular concern to the Amerindians who make up the majority of the population in Guyana’s hinterlands where most artisanal mining occurs. The Harvard Human Rights Program report points out that indigenous people, most of whom survive on subsistence agriculture, are disproportionately affected due to their dependence on waterways for food, transportation, communication, and sanitation.

Adapting to a “Changing World”

Over the past few months the environmental, social, and health effects caused by gold mining in Guyana has become serious enough to warrant a temporary governmental halt to the issuance of any new licenses. In the meantime, scientists employed by the Guyana Geology and Mines Commission are attempting to find a viable alternative to using mercury – the most damaging practice of artisanal miners – amid increasing pressure from the international community. In addition to polluting waterways and contaminating fish, mercury releases highly toxic vapors when it is burned away from gold, which can damage both internal organs and unborn children.

Damages from the run-away mining sector aren’t limited to the environment. The Amerindian Peoples’ Association in Guyana blames increases in prostitution, drug trafficking, and human trafficking on the country’s gold rush. According to the UN, “interior police investigated nearly 50 bush murders last year, about 40 more than normal, many from fights over gold and women or from drunken rum sprees by miners on time off.” Unlicensed mines and illegal aliens who cross the border from Brazil, compounded with a large smuggling operation that bypasses Guyanese gold taxes via Suriname, have left the government struggling to “enforce regulations, hire enough trained jungle mines inspectors, qualified geologists and other personnel to keep pace, and generally maintain order,” according to the UN.

On July 28, the Guyana Geology and Mines Commission issued a statement regarding the future of mining, and stressed the need to create a “holistic plan to have the industry adapt to a changing world.” For now it seems that complaints from Amerindian groups and other Guyanese citizens are the driving force in affecting change within the country, but opposition from interest groups such as the Guyana Gold and Diamond Miners Association is intense. The government has acknowledged international pressure too as a factor in its decision to suspend new permits and recently began a partnership with the United Nations Development Programme to develop a natural resource management plan. It remains to be seen exactly what measures will be taken to address the serious problems facing the Guyanese people as a result of gold mining, but given the strong economic imperative for artisanal miners and the severity of environmental and human health effects, action must be taken soon.

“It is plausible that key transitions in human evolutionary history have been driven in large part by climate change,” write Eugene A. Rosa and Thomas Dietz in “Human Drivers of National Greenhouse-Gas Emissions,” a literature review published by Nature Climate Change. “Changes in climate will doubtless be a key force in the future evolution of social systems, including all aspects of social, economic, and political life, while impinging on the health and well-being of the individuals who populate them.” Rosa and Dietz cite numerous studies to argue that nearly every facet of society will be affected by climate change. “The critical point,” they write, “is that population, affluence, technology, and all other drivers act not alone or additively but in a multiplicative fashion.” For example, rapid population growth can lead to an increase in urbanization, which generates “substantial demand for goods and services that can induce emissions in distant places.” They conclude that huge changes must be made in technology and consumption in order to combat the effects of climate change that are being caused by a growing population and an increasingly affluent world.

The United Nations’ 2012 Millennium Development Goals Report, released last month in New York City, announces that three of the eight major human development goals have been reached ahead of their 2015 targets. The Millennium Development Goals, set at a conference in 2000, were established to “uphold the principles of human dignity, equality, and equity at a global level.” The 2012 report indicates that the number of people living in extreme poverty has been halved since 1990; the proportion of people in the world without sustainable access to safe drinking water has also been halved; and more than 200 million slum dwellers have “gained access to either improved water sources, improved sanitation facilities, or durable or less crowded housing.” At the report launch, UN Secretary-General Ban Ki-moon noted that “these results represent a tremendous reduction in human suffering and are a clear validation of the approach embodied in the MDGs, but they are not a reason to relax.” Goals that have yet to be achieved include universal primary education; gender equality; reduced child mortality and improved maternal health; reducing rates of diseases such as HIV and malaria; and creating a global partnership for development.

“The discovery of gas reserves in the eastern Mediterranean comes at a time when world demand for energy is growing rapidly and many are questioning the reliability of supplies from North Africa and the Middle East,” said Emmanuel Karagiannis, assistant professor of Russian and post-Soviet politics at the University of Macedonia, in an interview at the Wilson Center.

The newly-discovered fields contain about 122 trillion cubic feet of recoverable natural gas reserves, 25 trillion of which are located within Israeli territorial waters. “That’s twice the reserves Libya has,” according to Karagiannis. The remaining fields have been claimed by the Republic of Cyprus, the Turkish Republic of Northern Cyprus, Syria, and Lebanon.

Europe currently depends on Russia for most of its gas supplies, so the new fields could provide an “important alternative source for European economies,” said Karagiannis.

The discovery also has the potential to increase stability in the region by serving as an incentive for nations to work together. “For example, Israel and Cyprus have come closer to each other in many respects, including military cooperation,” Karagiannis said. Greece and Israel have also strengthened their relationship, in part due to the historical relationship between Cyprus and Greece but also because the latter could serve as an energy hub to transport gas throughout Europe, he said. “In effect Israel, Greece, and Cyprus could form a new axis of stability in the region.”

“Turkey can also play a significant part in the business of transporting energy resources to Europe,” Karagiannis said, but Syria and Lebanon, the two other countries that lie adjacent to the newly discovered gas reserves, are less likely to benefit in the near future from the find, given their current political circumstances. “It’s very difficult to imagine their participation in the regional energy projects,” he said. Lebanon has tried and failed to sell offshore exploratory licenses twice due to its lack of a state petroleum administration, while the current uprising against President Bashar al-Assad is preventing any progress in Syria.

In part as a result of these political challenges, the gas fields also have the potential to generate conflict in the region. There will be a divide between “haves and have-nots,” explained Karagiannis. According to a report by the Institute for National Strategic Studies, “piping Israeli gas to the RoC [Republic of Cyprus] and then onto Turkey, which could be the gateway to the European market, is unlikely due to current tensions between Ankara, the RoC, and Tel Aviv.” Since the discovery of the fields, “Turkey has already issued military threats against Cyprus in order to stop the gas exploration process that is currently taking place in the Cypriot Exclusive Economic Zone,” Karagiannis said. The Israeli government issued a response to the threat, stating that they are committed to protecting energy infrastructure in the region.

The first new natural gas field in the region is expected to begin full-scale production this year, with two additional fields coming on-line over the next six years.

Two maps released to the public for the first time this month illustrate the vast wealth of mineral deposits in the war-torn nation of Afghanistan. The maps, created through a joint effort from the U.S. Geological Survey and Department of Defense Task Force for Business and Stability Operations, are the first of their kind to provide large-scale coverage of a country using a technology called hyperspectral imaging, which measures the reflectance of material on the Earth’s surface simultaneously across a continuous band of wavelengths broken up into 10 to 20 nanometer intervals. More than 800 million individual pixels of data were collected during a period of 43 days in 2007 by a NASA aircraft. Each data point was then “compared to reference spectrum entries in a spectral library of minerals, vegetation, water, ice, and snow in order to characterize surface materials across the Afghan landscape.”

Each data point was then “compared to reference spectrum entries in a spectral library of minerals, vegetation, water, ice, and snow in order to characterize surface materials across the Afghan landscape.”

Accompanying the release of the maps is a USGS study, completed in September of 2011, that largely confirms earlier reports from the DOD and USGS on the size of Afghanistan’s untapped mineral resources. The first reports received widespread media coverage last year, and updated estimates indicate that upwards of $900 billion worth of mineral reserves are present in a number of different forms including copper, iron, gold, and, most notably, more than one million metric tons of rare earth elements.

Scientists involved with the project believe that there may be even more reserves awaiting discovery. “I fully expect that our estimates are conservative,” said Robert Tucker from the USGS in an interview with Scientific American. “With more time, and with more people doing proper exploration, it could become a major, major discovery.”

Over the course of the study, scientists from the USGS and Afghan Geological Survey combined the newly-created spectral data with existing maps to identify 24 areas of interest (AOIs) that warranted hands-on investigation.

The two hyperspectral maps illustrate different parts of the electromagnetic spectrum. Shortwave infrared wavelengths reveal carbonates, phyllosilicates, and sulfates, while visible and near-infrared wavelengths show iron-bearing minerals, which yield products ranging from copper to rare earth elements and uranium. Each map classifies 31 different types of materials by color.

Although the hyperspectral maps only show mineral deposits on the surface, geologists were able to estimate what lies beneath by combining new data with samples previously taken from trenches, drill holes, or underground workings at the AOIs by Soviet and Afghan scientists. According to the USGS, “A number of the AOIs were field checked by USGS and DOD geologists between 2009 and 2011, and the previous geologic interpretations and concepts were confirmed.”

Actual Extraction: Not Easy

Afghanistan has been “scouring the globe for investors to develop its mines in an attempt to lift one of the world’s poorest nations out of misery through investment,” according to The Wall Street Journal. Contracts have already been awarded to China and India to develop copper and iron mines, respectively, and another round of bidding is currently in progress for four unexploited sites that are being closely eyed by countries such as the United States, Australia, and Turkey.

But significant hurdles remain in the quest to turn Afghanistan’s buried minerals into a steady source of income for the government and the Afghan people. Security is still a major concern and United States will pull out a vast majority of its combat troops by 2014. The government has established a Mines Protection Unit to guard sites where ground has already been broken, and plans to increase the size of the unit as necessary to provide security for all mining projects nationwide. For now the Afghan Ministry of Mines is only taking bids for projects in the more secure northern part of the country, where deposits of copper and gold are located. As the nation develops and stabilizes, massive resources of rare earth elements located in the notoriously volatile Helmand Province will open for bids.

Security isn’t the only factor affecting the country’s mining prospects. “If you want to do mineral resource development, there are two things you need to pay attention to: water and energy resources. Where is the power going to come from? You can’t develop these large mineral deposits without energy,” said director of the USGS program in Afghanistan, Jack Medlin, in an interview with EARTH magazine.

There are also the traditional pitfalls of developing extractive industries, especially in poor and conflict-prone countries, including corruption, inequity, land disputes, and environmental degradation. And the fact that Afghanistan is landlocked, making supply lines in an out of the country difficult (as the United States has discovered).

Despite the many hurdles, there is plenty of optimism for an Afghan future brightened by mineral wealth. The new data shows that previous reports of substantial resources were not far off, and the Afghan economy, which for years has relied on opium as its biggest export, could certainly use the help. “The prognosis is extremely encouraging and could play a significant role in recovery from decades of war,” USAID advisor Wayne Pennington told EARTH.

What they found when they first approached the U.K. defense establishment in 2006, was surprising. “They opened [that] door wide open and said, ‘actually, you know what, we’ve been looking at this, we’ve been concerned about this for a long time, and we’ve already started including it in our long-term planning and strategic thinking.’”

“One of the reasons that the defense community has been looking at this issue is that they have a longer-term vision, if you like, than other departments,” Feakin said. “They have to think about procurement decisions which are going to be stretching out…up to 30 years into the future, so there are bigger demands on them to be thinking about these kinds of strategic issues.”

Feakin co-authored International Dimensions of Climate Change, a 2011 report for the British government which highlights the security threats and challenges, both internal and external, that the U.K. will face as result of climate change.

While the defense community acknowledged the need to include climate change in their planning processes, members of the policymaking community expressed concern that they did not, “have enough detailed understanding of what this [climate change] is going to mean in a security paradigm,” said Feakin. To meet that need, RUSI has been conducting regional and country-based studies in order to determine how things might play out.

Dialogue on the issue has transcended Great Britain and is now taking place among member states of the European Union, although Feakin notes that, “there’s perhaps more hesitancy in terms of framing the debate in the security paradigm and perhaps a slight perception that it might be leading us down the wrong path when mitigation efforts should be at the top of the order of play.”

Despite these ongoing debates, Feakin believes that the security aspect of climate change helps to “make a comprehensive case that we have a situation that does have to be dealt with and there are going to be multiple players in that.” Efforts to address climate change will be civilian-led, but the defense community will play an important supporting role in the future, he said.

“It’s something we have to plan for and we will be part of the response.”
